I can't locate where to fix this error stating "Instance member can't be accessed using static access"

I am getting this error "Instance member can’t be accessed using static access" and I can’t locate where as I have data related to the error in another class. Am new to Dart Flutter and still learning, so it all isn’t making sense to me much.

Code where am getting this error is at .getLocationWeather():

 void getLocationData() async {
    var weatherData = await WeatherModel.getLocationWeather();

    Navigator.push(context, MaterialPageRoute(builder: (context) {
      return LocationScreen(
        locationWeather: weatherData,
      );

Below is the class’ code where getLlocationWeather() is located.

import 'location.dart';
import 'networking.dart';

const apiKey = 'e72ca729af228beabd5d20e3b7749713';
const openWeatherMapURL = 'https://api.openweathermap.org/data/2.5/weather';

class WeatherModel {
  Future<dynamic> getCityWeather(String cityName) async {
    NetworkHelper networkHelper = NetworkHelper(
        '$openWeatherMapURL?q=$cityName&appid=$apiKey&units=metric');

    var weatherData = await networkHelper.getData();
    return weatherData;
  }

  Future<dynamic> getLocationWeather() async {
    Location location = Location();
    await location.getCurrentLocation();

    NetworkHelper networkHelper = NetworkHelper(
        '$openWeatherMapURL?lat=${location.latitude}&lon=${location.longitude}&appid=$apiKey&units=metric');

    var weatherData = await networkHelper.getData();
    return weatherData;
  }

>Solution :

Simply add the brackets around to make it non-static. As following:

var weatherData = await WeatherModel().getLocationWeather();
